Same thing with me! After going to ENTs for 5 years they all told me “nasal steroid sprays, antihistamines, nasal deviation”. The nasal steroids sprays and antihistamines never worked, so I thought surgery is the only option. I did an MRI of my brain for another reason, and there I go with the scan to the ENT, turns out I have huge turbinate swelling and no nasal deviation. I need to try more meds now before going in for surgery (turbinate reduction surgery).
